I've upgraded to Premiere Pro 14.4 from 14.3.2 as suggested by the Adobe Creative Cloud.
14.4 features the Rec.2100 HLG environment and I was looking forward to it.
However I use the Samsung Galaxy Book 12 (i5-7200U with Intel Graphics HD620) when I'm on the go and now it lags like crazy during editing. I re-installed 14.3.2 and it works as always: it doesn't fly but it's useable while 14.4 pushes the CPU to 100% all the time slowing down itself and the whole system.
Did anyone experience the same?
Editing, Hardware or GPU, User interface or workspaces
No update to the Intel graphics. Actually re-installing 14.3.2 the editing speed is back to normal. The act of having 14.4 open with a simple single 4K video file in the timeline with no live playback gets my computer into trouble while 14.3.2 doesn't establish such a high CPU usage.
I discovered the severe lag of PremierePro 14.4 (having an impact on the whole Win10 2004 system) is caused by editing the Avid DNxHR HQX video format. And that did NOT occur on PremierePro 14.3.2 that worked perfectly fine with my DNxHR HQX UHD footage. Accidentally I started to edit a PreRes HQ 422 on 14.4 and everything worked fine. As fast as 14.3.2, as it should be.
14.4 must have problems editing the Avid DNxHR video format.
These are the specs of two of my files :
